Dickens's literary success began with the 1836 serial publication of The Pickwick Papers.
Within a few years he had become an international literary celebrity, famous for his humour, satire, and keen observation of character and society.
After his death, the Duchess, already suffering from arteriosclerosis, isolated from the royal family and with no close blood relations, was left relatively alone.
At first she had the services of the distinguished lawyer, Sir Godfrey Morley, of Allen & Overy.
His 1843 novella, A Christmas Carol, remains popular and continues to inspire adaptations in every artistic genre.
The drama was relived with the publication of their memoirs, the emergence of his film, A King's Story, and then the moment of his death in May 1972, when the Duchess of Windsor joined his family for the funeral, before gradually descending into the long illness from which she was eventually released in her 90th year in 1986.
While the Duke lived, there was no mention of Maitre Suzanne Blum, the formidable lawyer who rose to public attention in the years following the Duke's death and became the guardian of the Duchess in her long decline. Originally she was the wife of their legal representative in Paris, but she became their 'Executeur Testamentaire', and in her words the 'defender of the moral rights and interests of the Duchess of Windsor'.
The Abdication of Edward VIII in 1936 passed into history though the protagonists lived on.
Every now and again in the 1960s there were photographs of the Duke and Duchess of Windsor, arriving at a party, he a dapper if worn figure with sad, spaniel-like eyes, his wife increasingly elegant and brittle.
